Sustainable business starts with insight. With our CO₂ sustainability calculator, you can easily calculate the impact of reusing network, server and server hardware. Every choice for circular IT saves CO₂ emissions and e-waste. So you contribute directly to a more sustainable future – and you can prove it with an official CO₂ certificate.
Why choose circular IT?
Circular IT goes beyond recycling. By reusing and refurbishing existing hardware, you reduce environmental impact and extend the life of valuable equipment. That gets you the following:
- Reduce carbon emissions
Reduce manufacturing impact by reusing hardware. - Less e-waste
Reduce electronic waste through responsible lifecycle management. - Higher residual value
Old hardware yields more when purchased and reduces replacement costs.
